bump version

add messenger binary

Just vignette changes

add support for LaTeX output by using pandoc to convert cells

Added some extra bits to the vignette

Everything seems to be finally working - except perhaps the assignment of variables to the global environment when you're working with R markdown interactively, but that's not currently important.

Something screwy still going on with extractTables

Simple ANOVA converter. It works, but I think there's still something wonky with the vector_map stuff in extractTablesToEnv

update .gs_nearest_gen_headers_xpath

Removed a whole lot of leftover space from the HTML. Changes nothing but makes life easier when debugging

* all save tables options work now

Still need to implement include

extractTables almost working properly. Works most of the time - vector_map isn't

Extracting tables - not working yet

Starting to add code for saving tablular output.
